I'm checking label module in /mod/label. I want to disable cahing in dis file: /mod/label/lib.php  -> function label_get_coursemodule_info:

function label_get_coursemodule_info($coursemodule) {
    global $DB;

    if ($label = $DB->get_record('label', array('id'=>$coursemodule->instance), 'id, name, intro, introformat')) {
        if (empty($label->name)) {
            // label name missing, fix it
            $label->name = "label{$label->id}";
            $DB->set_field('label', 'name', $label->name, array('id'=>$label->id));
        }
        $info = new cached_cm_info();
        // no filtering hre because this info is cached and filtered later
        $info->content = format_module_intro('label', $label, $coursemodule->id, false);
        $info->name  = $label->name;
        return $info;
    } else {
        return null;
    }
}

in this line $info = new cached_cm_info(); caching of outputs is commanded. How I can disable caching. How I can send dynamic data here? is there any command to refresh cached files every time. Another matter to say: I checked this code, after first time of calling this function, it will not called again an caller is /course/lib.php and I do not want to edit course/lib.php!
